IMPROVEMENT IN BOLTS.

Specification forming part of Letters Patent No. l47,973,dated February24, 1874; application filed February 4, 1874.

T0 all whom it may concern Be it known that I, JOHANN PEYER, of VVahring, near Vienna, in the Empire of Austria, have invented a new andImproved Bolt-V Lock; and I do hereby declare the following to be afull, clear, and exact description thereot', which will enable thoseskilled in the art to make and use the sam e, reference being had to theaccompanying drawing,'forming part of iny'speciication, in whichdrawing- Figure l represents my lock .in section, as applied to a dooror window. Fig. 2 is a sectional face view of the lock detached.

Similar letters indicate cor-responding parts.

This invention consists in the employment of a double crank, arranged onthe lock-spindle, for operating bolt-slides, each ot' which is providedwith a socket for the reception of bolt-pins, the bolts ot which are letinto the stile of a folding door or window, and one of which carries ahook that projects from said stile, in such a manner that when my lockis applied to one of the two sashes of a French window it serves,through the bolts, to brace this sash, and, through the hook, to retainor lock therewith the second one, the latter'being mortised for thereception of the hook. By rotating the crank, a reciproca-ting motion isimparted to the bolt-slides, whereby the bolts are locked or unlocked,as desired.

In the drawing, which shows my invention in a locked posit-ion, theVletters A A designate the stiles of two sashcs of a French window, forwhich my invention is particularly intended, each of which sashes ishinged, and is made to close on the other, as shown. B is the case of mylock, which is mortised in the surface of the outer rail of thelockingstile. The handle I) carries a stem or spindle, E, extending intothe lock, on which spindle is mounted a double crank, F, composed ofthree disks, provided with eccentric pins a a, placed on oppositesurfaces of the middle disk, and opposite each other on the edgesthereof, forming a connection between the middle and the two outerdisks. Each of the crank-pins a a moves in slots b, Fig. 2, formed inone end of plates or slides G, the other end of which slides carrysocket-pieces c c,

which receive the pins cl d of bolts H H. These pins d d of the boltswork in slots c e of the lock-case, and the bolts are lot into channelsI I, extending above and below the lock in the locking-stile, whichchannels are provided with a lining of metal to reduce friction of thebolts, and to preserve the wood. One of the bolts is provided with ahook, J, which projects therefrom through the stile A, which is slottedat f, for the passage and working of the shank of the hook. A mortise,K, is formed in the stile next and opposite to the hook J, such mortisebeing concealed by a front plate, which is slotted for the admission ofthe hook. The bolts H H are retained in suitable sockets in the floorand ceiling, and the hook J catches behind the frontplate in themortise.

In order to withdraw the bolts, the handle Dis turned through ahalfcircle, when the position of the crank-pins is reversed, and,operating the bolt-slides, the bolts are drawn toward each other, thehook J being at the same timefraised or brought on a level with the slotin the mortise-plate, so that such hook is released, and is withdrawn,in opening the sashes, without obstruction.

It will be observed that my lock is made entirely independent of thebolts, and can be readily removed or taken out of the sashes to preserveit (the lock) from moisture or wet in washing the windows.

What I claim as new, and desire to secure by Letters Patent, is i Thedouble crank F, arranged on the lockspindle, for operating theboltslides G, each of which is provided with a socket for the receptionof bolt-pins, the bolts H H of which are let into the stile A of afolding door or window, and one of which carries a hook, J, projectingfrom said stile, and operating substantially as herein described.

This specication signed by me this 25th day of November, 1873.

JOHANN PEYER.
